Incidental Detection of Lipomatous Hypertrophy of the Interventricular Septum on FDG PET/CT.

ABSTRACT: Cardiac lipomatous hypertrophy is a rare benign condition almost exclusively involving the interatrial septum. Interventricular septum involvement is seldom noted, with only a few documented case reports demonstrating the finding on various modalities such as ECHO, CT, and MRI. FDG PET can be a surrogate marker for lipomatous hypertrophy of the interventricular septum. Here, we describe a case of incidentally detected lipomatous hypertrophy of the interventricular septum on FDG PET/CT in a patient with squamous cell carcinoma of the oropharynx.

Unveiling the Allergy-Meniere Connection: Exploring the Impact of Allergen Positivity on Meniere's Disease Severity.

Meniere's Disease is a rare ear disorder that can cause severe morbidity to the patient and has no definitive treatment to date. Endolymphatic hydrops is the critical event. Though symptomatology is well understood, the exact etiology of Endolymphatic hydrops attack is still unclear. Twenty-five consecutive patients of Meniere's Disease diagnosed in the Vertigo clinic aged 12 to 70 years were included. Their allergic status was evaluated using a skin prick test. Allergic and non-allergic patients were then identified. Comparison between the two groups was made to identify the effect of allergy on the severity of symptoms using vertigo scales, Functional level scale, Dizziness handicap index, and Pure tone average staging. The prevalence of allergy among Meniere's Disease patients was 56%. The most common allergen found in our study was tyrophagus(n = 8). Polysensitization was more common(n = 12). Airborne allergens were more common than food allergens. There was no significant relationship between the severity scales and the allergen positivity status (p > 0.05). The prevalence of allergy is more among patients with Meniere's Disease. The Endolymphatic sac is allergy prone. The occurrence of endolymphatic hydrops may be due to a cross-reaction of allergen-induced IgE antibodies to self-antigen. Management of the specific allergen may help decrease symptomatology in these patients. Allergen-specific therapies have a promising role in the treatment of allergic conditions and provide a long-term symptom-free period in affected individuals. This can be applied in patients with Meniere's Disease having associated allergic features based on their skin prick test results.

Prevelance of Common Aeroallergens in Allergic Rhinitis and its Correlation with Bronchial Asthma: A Study on 798 Patients by Skin Prick Test.

Allergic rhinitis affects 30% of the Indian population (Dey et al. in Int Arch Allergy Immunol 178:60-65, 2019). Patients can be sensitive to single or multiple allergens. Polysensitization is more common (Bousquet et al. in Ann Epidemiol 20:797-803, 2010; Arbes et al. in J Allergy Clin Immunol 116:377-383, 2005). Sensitization to multiple allergens may have a role in the severity and the association of Asthma in such patients. A total of 798 patients with allergic rhinitis (SFAR ≥ 7) were included. Disease severity and associated symptoms were evaluated using questionnaire. Each patient underwent a Skin prick test with an allergen panel of 35 allergens each (Annesi-Maesano et al. in Allergy 57:107-114, 2002) and the results were evaluated to study the association of asthma and severity of Allergic rhinitis. Data consisting of 389 (48.7%) males and 409 (51.3%) females were assessed. A total of 82.2% of the study population of symptomatic patients were sensitized to at least one of the allergens. Seventy patients (8.78%) had associated asthma. Forty-four patients were polysensitized and fifteen were mono sensitized. Among polysensitized patients, 36 patients had sensitization to at least 6 different allergens. Dermatophagoides pteronyssinus was the most common allergen among asthma patients. This study provides a thorough knowledge of locally prevalent aeroallergens which is essential for the prompt diagnosis and treatment of allergic patients. Skin prick test can be a non-invasive vital tool in analyzing patterns of allergen exposure, the prevalence of allergen, sensitizing potential of different allergens in that specific geographic area.

Development of Phonemically Balanced Passage, Oral Passage, and Nasal Passage in the Punjabi Language.

The primary aim of the study was to develop phonemically balanced passage, Oral passage and Nasal passage in Punjabi language. Development of the passage: The words in the passage were chosen to represent the way sounds are distributed in spoken Punjabi language, and the relative phonemic distribution of each word inside each paragraph matched how frequently each sound occurs in Punjabi. The paragraph was constructed using words that were rated as extremely familiar and familiar. The developed passages were given to five speech-language pathologists for the purpose of content validation. 100 people with normal hearing between the ages of 18 and 25 were enrolled in the study (50 female and 50 male). Each subject's nasalence was measured using a Nasometer. The individuals were given passages written in Punjabi to read, and their nasalence scores for each text were recorded. The nasalance mean for Punjabi phonemically balanced passage was 36.41 ± 4.61% and 38.57 ± 4.22% in male and female subjects. The Punjabi oral passage mean were 27.36 ± 4.14% and 28.46 ± 4.01% in male and female subjects. The means for Punjabi nasal passage were 46.15 ± 4.09% in male subjects and 47.04 ± 4.91% in the female subjects. The Intraclass correlation coefficient for Female and male subjects for the Punjabi Phonemically balanced passage, Punjabi oral passage, Punjabi nasal passage were 0.904, 0.945; 0.807, 0.909, and 0.956, 0.913 respectively. The developed passages have good test retest reliability and their normative scores can be used for assessment of different resonance disorders.

Sinonasal and Olfactory Quality of Life in Endoscopic Pituitary Surgery and Time Interval to Olfactory Recovery: A Comparative Prospective Study.

Background and Objective: Superior turbinate manipulation is often required in cases of narrow cavities and expanded endonasal approaches with concern for olfaction. The objective of the study was to compare the pre- and postoperative olfactory function in patients undergoing endoscopic endonasal transsphenoidal pituitary excision with and without superior turbinectomy, using the Pocket Smell Identification Test and the quality of life (QOL) and Sinonasal Outcome Test-22 (SNOT-22) scores, irrespective of the extension (Knosp grading) of pituitary tumors. We also aimed to identify olfactory neurons in the excised superior turbinate with immunohistochemical (IHC) stains and correlate them with clinical findings. Materials and Methods: The study was a prospective, randomized study performed in a tertiary center. Two groups A and B, with superior turbinate preserved and resected, respectively, during endoscopic pituitary resection, were compared using pre- and postoperative Pocket Smell Identification Test and QOL and SNOT-22 scores. The superior turbinate was subjected to IHC staining to identify the presence of olfactory neurons in patients with tumors of pituitary gland requiring endoscopic trans-sphenoid resection. Results: Fifty patients with sellar tumors were enrolled. The mean age of patients in this study was 46.15 years. The minimum age was 18 years and the maximum was 75 years. Of the 50 patients in the study, 18 were female and 32 were male. Eleven patients had more than one presenting complaint. Loss of vision was the commonest and altered sensorium was the rarest symptom. Conclusion: Superior turbinectomy is a viable option to gain wider access to sella without affecting the sinonasal function, quality of life, and olfaction. There was doubtful presence of olfactory neurons in superior turbinate. The extent of tumor resection and postoperative complications were unaffected and statistically nonsignificant in both the groups.

Surgical Field Quality in Trans-Nasal Endoscopic Surgeries Using Lignocaine Infusion and Dexmedetomidine Infusion. A Prospective Randomized Control Study.

Trans-nasal endoscopic surgery (TNES) is a helpful diagnostic and therapeutic modality in otorhinolaryngology surgeries and requires controlled hypotension for better visualization of the surgical field. Recent literature shows evidence of intravenous Lignocaine infusion to produce the controlled hypotension. The study aims to assess and compare the effects of Lignocaine (LIG) and Dexmedetomidine (DEX) infusion with respect to surgical field quality. 101 Consenting adult patients undergoing elective TNES were double-blinded, randomly allocated in one of the two groups and received either DEX infusion of 0.5ug/kg/hr (n = 51) or LIG infusion of 1.5 mg/kg/h (n = 50) after a loading dose. Surgical field score (SVF) as the primary outcome and secondary outcomes such as variations in hemodynamic parameters, the requirement for rescue agents and total blood loss were recorded. Both the groups were comparable with respect to patient demographics, total duration of anesthesia and surgery. SVF scores were significantly better in the LIG group during the first 105 min of the surgery (p < 0.05). In response to intubation, hemodynamic parameters were lower in LIG group. The requirement of other adjuvant drugs, total blood loss (166.40 ml vs. 251.17 ml) and extubation time were also significantly lower in the LIG group. The study concludes that intravenous Lignocaine gives a better surgical field in the first 105 min of surgery, comparable hemodynamics and decreased blood loss in patients undergoing TNES as compared to Dexmedetomidine infusion. Hence its role as an agent for controlled hypotension during TNES surgery is promising.

As the virus sowed, the fungus reaped! A comparative analysis of the clinico-epidemiological characteristics of rhino-orbital mucormycosis before and during COVID-19 pandemic.

BACKGROUND: The sudden surge of mucormycosis cases which happened during the second wave of COVID-19 pandemic was a significant public health problem in India. OBJECTIVES: The aim of this study was to analyse the clinico-epidemicological characteristics of the mucormycosis cases to determine the changes that had occurred due to COVID-19 pandemic. METHODOLOGY: A retrospective cross-sectional study was conducted at the Department of Otolaryngology Head and Neck Surgery, PGIMER, Chandigarh, India. Patients diagnosed with rhino-orbital mucormycosis were categorised into the following groups: Pre-pandemic(May 2019 to April 2020), Pandemic Pre-epidemic (May 2020 to April 2021) and Epidemic (1 May 2021 to 12 July 2021). The epidemiological, clinical and surgical data of all the patients were retrieved from the hospital records and analysed. RESULTS: The epidemic period had 370 cases, compared with 65 during pandemic period and 42 in the pre-pandemic period. Diabetes mellitus was seen in 87% of cases during epidemic period, 92.9% in the pre-pandemic period and 90.8% in the pre-pandemic pre-epidemic period. The proportion of patients suffering from vision loss, restricted extra-ocular movements, palatal ulcer and nasal obstruction was higher in the pre-epidemic groups, and the difference was significant (p, <.01). There was no history of oxygen use in 85.9% of patients and no steroid use in 76.5%. The death rates were the lowest during epidemic (10%). CONCLUSION: COVID-19 has caused a statistically significant increase in the number of mucormycosis infections. The mortality and morbidity which showed an increase during the first wave of COVID-19 decreased significantly during the epidemic period.

Tele-Otolaryngology at a Tertiary Care Center in North India During COVID-19 Pandemic Lockdown: A Validated Patient Feedback Questionnaire Based Study.

Providing medical care using the telecommunication networks holds the promise of increased access and efficiency of healthcare particularly during global emergencies like the Coronavirus disease 2019 (COVID-19) pandemic. Most of the hospital setups worldwide have put telemedicine into practice ever since the onset of the COVID-19 pandemic. This study aimed at assessing the effectiveness of Tele-otolaryngology (TO) at a tertiary care centre during the pandemic lockdown. A validated patient feedback questionnaire was developed and distributed to 2577 patients who utilised the TO mobile health service at our institute. Patient feedback-based assessment of TO effectiveness during COVID-19 lockdown was carried out. The validated questionnaire in English and Hindi was statistically robust with Cronbach's alpha value of 0.808 and 0.886 respectively. 1751 patients completed their feedback to the questionnaire. 97.5% utilised WhatsApp for TO consultation. 15.2% patients were detected of Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection with TO guidance. Up to 75% patients had a positive response to the questionnaire and 91.1% opined of savings achieved either with travel time, cost incurred or the treatment time. With respect to patient health status, 71.5% recovered, 20.1% had no change and 8.4% deteriorated with a mortality rate of 1.65%. Telehealth in otolaryngology during the COVID-19 pandemic lockdown was indispensable in managing exigencies. Redesigning of clinical protocol and technical constraints, clinician training and a validated patient feedback questionnaire would effectively bestow upon the global emergencies.

Role of Oncofetal Protein CR-1 as a Potential Tumor Marker for Oral Squamous Cell Carcinoma.

Cripto-1 (CR-1) is an oncofetal protein with its role as a key factor in early process of carcinoma has been evaluated in cases of various cancers. However, very few studies have reported its role in oral cancer, which is the sixth most common cancer around the world, particularly with high prevalence in developing countries. Oral squamous cell carcinoma (OSCC) is the most predominant (90%) of all the histological types of oral cancer. Late detection, associated with increased morbidity and mortality, is mainly attributed to non-availability of a suitable biomarker for the disease. In the present pilot study, we have evaluated the role of soluble CR-1, in serum as a potential tumor marker for OSCC. CR-1 was estimated using sandwich ELISA in serum samples of 50 biopsy proven OSCC patients (pre and post treatment) along with age and gender matched healthy controls. Immunohistochemistry was also done in corresponding tumor tissue sections to check the expression of CR-1. Pre-treatment CR-1 was found to be 2.25-fold higher in serum of OSCC patients as compared to control (p < 0.0001***), which was reduced to 1.6 folds post treatment (p = 0.0006***). CR-1 levels were comparatively higher in early stage of disease. Upon IHC 80% of the cases were found to be positive for CR-1. This study provides evidence that serum levels of CR-1 are elevated in patients of Oral Squamous Cell Carcinoma, which decrease post treatment. Also, the association of expression of protein with tumor progression predicts CR-1 as a molecule that can be further evaluated as a potential tumor maker in OSCC.

Management of CVJ tuberculosis: the changing paradigm.

BACKGROUND: The literature seems fractured for the management of craniovertebral junction (CVJ)-tuberculosis (TB). Presently, non-surgical management has been in vogue for neurologically intact patients. On the contrary, severely disabled cases of CVJ-TB continue to attract discussion, tilted towards surgical intervention. We present our experience with the non-surgical management of CVJ-TB tailored to their neurological status. METHODS: Authors managed 37 cases (2004-2019; age 1-57 years, mean 36 years) of CVJ-TB, of which eighteen (18/37, 48.6%) were severely disabled (Nurick grade ≥ 3) with a mean follow-up of 84 months (48-192 months). Irrespective of the clinical status and radiological findings, all patients were managed on medical management only. Needle aspiration established pathology in 23 (62.2%) cases, while 9 (24.3%) cases required drainage of an abscess. All patients received 18 months of anti-tubercular therapy (ATT). In patients with Nurick grade ≥ 3 and documented AAD, we applied halo vest for 12 months to achieve cervical immobilization. Only hard cervical collar for 3 months was prescribed in patients with no documented AAD. RESULTS: All minimally disabled cases (Nurick grade ≤ 2, n = 19) responded favorably (n = 18) to ATT, except for an infant, who succumbed to irreversible hypoxic brain damage due to the obstructed aero-digestive gateway. Of the severely disabled cases (Nurick grade ≥ 3, n = 18), 16 cases had favorable outcomes with only external orthosis (12) and 18-month ATT. One patient succumbed to multiple cerebral infarcts, while one required realignment surgery at CVJ due to fusion in malaligned position. CONCLUSION: The authors conclude that the disability grading of CVJ-TB is pertinent only for assessing the functional disability of patients at presentation, with minimal relevance in deciding its management strategy. Irrespective of neurological disability, almost all patients respond favorably to external immobilization and ATT.

Investigation of the Paediatric Tracheostomy Decannulation: Factors Affecting Outcome.

INTRODUCTION: Evidence for factors determining paediatric tracheostomy decannulation vary extensively; therefore, this prospective observational study aimed to investigate these factors. MATERIALS AND METHODS: In total, 67 consecutive paediatric patients (<12 years old) who referred to the Department of Otolaryngology, (Postgraduate Institute Medical Education and Research),(Chandigarh), India, for decannulation were included and evaluated for contributing factors in this study. Parental counselling was performed, and informed consents were obtained from them. The patients underwent detailed work up including X-rays of airway/soft tissue neck (STN) and endoscopic assessment under anaesthesia for evaluating airway patency. Decannulations were attempted post assessment and followed up one month to classify decannulation as success or failure regarding the removal of the tracheostomy tube. RESULTS: Totally, 61 patients out of 67 cases were successfully decannulated, whereas six children failed the decannulation. Moreover, the duration of tracheostomy (Pearson's Chi-square 35.330, P=0.013), indication of tracheostomy (Pearson's Chi-square 21.211, P=0.000), STN X-Ray (Chi-square 43.249, P=0.000), and bronchoscopic findings (Chi-square 67.000, P=0.000) were significantly associated with the outcome of decannulation. However, decannulation outcome had no significant correlation with various factors, such as the duration of intubation preceding tracheostomy, duration of ventilation, tracheal swabs, and antibiotic therapy. CONCLUSION: The STN X-ray is an independent predictor, and it is recommended for paediatric tracheostomy decannulation. Moreover, bronchoscopic assessment should be performed in children having doubtful infra-stomal airway. Duration of tracheostomy significantly affects decannulation outcome. However, intubation duration preceding tracheostomy and duration of assistive ventilation have no direct effects on the outcome of decannulation. In children, gradual decannulation should be preferred and one month follow up is adequate for deciding decannulation outcome.

Endoscopic management of congenital nasal meningoencephaloceles: a short series of 15 paediatric cases.

PURPOSE: To retrospectively analyse surgical management of clinico-radiologically proven nasal meningoencephalocele amongst children and results of repair with single-layer septo-mucosal flap at a tertiary skull base surgery centre in north India. METHODS: Fifteen children with clinic-radiological nasal meningoencephaloceles with or without CSF rhinorrhoea were included. Radiological scans included CT scans and MRI scans for all cases to delineate soft tissue and bony architecture. All children underwent endoscopic excision of encephaloceles and repair of the skull base defect. RESULTS: The authors were successful in fourteen cases. Successful cases included 4 children less than 6 months of age who underwent single-layer rotated septo-mucosal flaps, thereby avoiding donor site morbidity. CONCLUSION: As endoscopic excision of nasal encephalocele is an established management approach, the authors take the concept of minimally invasive surgery a step further by successfully managing these lesions with single-layer repair. Vascularized septo-mucosal flap seems to be the only determining factor for a successful repair for congenital meningoencephalocele. However, a prospective study comprising a larger subset of patients would substantiate the assumption.

Nasal Chondromesenchymal Hamartoma.

Nasal chondromesenchymal hamartoma (NCMH) is a rare, benign lesion of the sinonasal tract. It usually presents as a polypoid mass in infants and older children. Imaging studies and endoscopy are required to delineate the extent of the lesion and aid in its excision. This unusual lesion is composed of proliferating mesenchymal and cartilaginous elements. Recently, a genetic association between NCMH and DICER1 mutation has been established. It is important for pathologists to be familiar with this entity to avoid misdiagnosis since the lesion is benign and surgical excision is curative.

Evaluation of Multimodality Management of Adenoid Cystic Carcinoma of the Head and Neck.

Adenoid cystic carcinoma is a relatively rare tumour arising from salivary glands of head and neck region. Surgery and radiotherapy form standard treatment modalities in the management of this tumor. In this analysis we present results of multimodality treatment in our cohort of patient. This retrospective analysis evaluated results of treatment in forty patients diagnosed with adenoid cystic carcinoma of the head and neck. Evaluation was done to identify prognostic factors affecting the disease free survival. A median disease free survival of 34 ± 2.42 (Median ± SE) versus 10 ± 5.45 months was seen in patients undergoing surgery followed by post operative radiotherapy versus radiotherapy alone (P = 0.01). A radiotherapy dose more than 60 Gy was associated with a better disease free survival compared with patients receiving less than 60 Gy (P = 0.01). Positive surgical margins and perineural invasion were associated with a poor treatment outcome (P = 0.02) Patients with c-kit positive status showed a poor local control rate (P = 0.05).

Frontal pyomucocoele as forehead swelling in a five-year-old girl.

Mucocoeles are slow-growing, locally aggressive, mucus-containing cysts, lined by epithelium, which, when infected, are called pyomucocoeles. We present the case of a five-year-old girl who presented with a frontal pyomucocoele requiring decompression and adequate antibiotics.

Pindborg Tumor Presenting as a Nasal Polyp: Immunohistology and Ultrastructural Features of a Rare Case, With Review of the Literature.

Calcifying epithelial odontogenic tumor, also known as Pindborg tumor, is a rare benign odontogenic tumor. This tumor predominantly involves the mandible, though the maxilla can also be involved in some cases. The involvement of maxillary sinuses, however, has been previously reported in only 8 case reports English literature. These patients chiefly presented with nasal obstruction along with epistaxis or proptosis in rare cases. However, a primary presentation as nasal polyp is unheard of. We present a rare case of calcifying epithelial odontogenic tumor presenting as a nasal polyp, posing a diagnostic difficulty.

Apoplexy in an intradural clival chordoma causing intraventricular bleed.

BACKGROUND: A few cases depicting apoplexy in a chordoma have been reported. Rarely, this intratumoral bleed may spillover into intracerebral or intraventricular regions. CASE DESCRIPTION: The authors report an intradural variety of clival chordoma presenting with apoplexy and spillover of blood into lateral ventricle. Clinical presentation, radiological scans, and relevant literature is also described. CONCLUSIONS: In a stable case of clival chordoma, intratumoral bleed or apoplexy may cause rapid neurological worsening and warranting urgent surgical intervention.

Comparison by objective parameters in patients with chronic rhinosinusitis managed medically and surgically (with and without powered instruments).

OBJECTIVE: To compare mucociliary clearance time and quality of life in patients who underwent sinus surgery using conventional and powered instruments, and in patients who were treated nonsurgically. METHODS: A total of 151 patients with chronic rhinosinusitis were included. Fifty-four patients were treated conservatively, 48 patients were managed surgically by using conventional instruments and 49 patients were managed by using a microdebrider. Kupferberg nasal endoscopy grades, 20-item Sino-Nasal Outcome Test scores, Lund-Mackay scores, and mucociliary clearance time were analyzed. RESULTS: On comparison among the groups, it was found that there was a significant difference between group A (nonsurgically treated) compared with group B (surgery by conventional means) or group C (surgery with microdebrider) in nasal endoscopic grades, Lund-Mackay scores, 20-item Sino-Nasal Outcome Test scores, and mucociliary clearance time. However, in comparison between groups B and C, there was no statistically significant difference. CONCLUSION: Mucociliary clearance time tended to recover after starting treatment for chronic rhinosinusitis both after conservative treatment and after surgical treatment. Surgery provided better improvement in different objective scores in chronic rhinosinusitis. There exists no statistical difference in parameters independent of the instrument used for surgery.

Successful endoscopic endonasal repair of nasal meningoencephalocele in a 21-day-old neonate.

INTRODUCTION: Indications of surgical intervention in congenital nasal meningoencephaloceles includes presence of cerebro spinal fluid rhinorrhea having a risk of causing meningitis, episodes of prior meningitis and bilateral nasal obstruction causing respiratory difficulty in these obligate nasal breathers. Many authors would like to wait till the patient attains the age of 2 to 3 years for repair of the defect due to surgical feasibility. However, early intervention prevents further episodes of meningitis in the future. We present the youngest patient of nasal meningoencephalocele successfully repaired via endoscopic approach. CASE REPORT: A 21 days old neonate was referred to us with a nasal meningoencephalocele with active cerebrospinal fluid rhinorrhoea. Radiological investigation showed a cribriform plate defect on the right side. Repair was done by endoscopic route by multi-layered closure of the defect which was augmented with a mucoperichondrial flap from the septum. Patient was asymptomatic in the post-operative follow up period and did not have any episode of meningitis till date. CONCLUSION: Early repair by transnasal endoscopic route is a feasible surgical option for congenital anterior skull base defects with meningoencephaloceles to prevent further episodes of meningitis. This is feasible even in the neonatal period due to improved technique and instrumentation now available for endoscopic nasal surgeries.
